Dear,

I would know how to include new statements in specific CFG blocks
during compilation. There are resources for this?
During the profile instrumentation, codes are included on the edges of
the CFG. How to include code in the block?
At first I want to include a line code in each block. This line will
call a function I created in libgcov. This function receive a
parameter of type int or unsigned.

Thanks,
Harry

I think the options here are writing a compiler plugin or modifying gcc
itself.  For information on plugins you can start at

At first I am thinking in modifying the GCC. But I wonder if there are
features that help to add new statements on specific points of the
program (in this case, specific blocks of CFG.) I'll do it at the time
the compiler is inserting codes to profile.
